The AirTAC GR20006JNT AirTAC Air Pressure Regulator NPT1/8 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 MPa (7 - 130 psi) with PT1/8" ports, ordered without a gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The GR20006JNT is an AirTAC GR-series air pressure regulator for compressed air only. It does one job: reduce and hold a stable downstream pressure from line supply up to 1.0 MPa (145 psi) inlet, adjustable across 0.05-0.9 MPa (7-130 psi). This configuration is the GR200 size with a 1/8 in NPT port, the standard (not low-pressure) regulator type, supplied without a gauge (code N) and without a mounting bracket (code J). As a GR unit it contains no filter, no bowl and no drain, and it performs no lubrication - regulation only. Operating temperature is -20 to 70 C, wider than the rest of the G-series families, and the housing is panel-mountable if you prefer that to bracket mounting.
This is a genuine AirTAC part from the GR200 size class, the smallest step in the GR range, which steps up through GR300, GR400 and GR600 for larger ports and higher flow. Across the series you can order PT, G (BSPP) or NPT threads, add a gauge or omit it, specify the low-pressure type (L) where set pressures stay at or below 0.4 MPa, and choose bracket or no bracket. Flow for this family is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures against your application before you order.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| 06 | Port size PT1/8". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom rather than from a single rated figure.

Feeding a compact clamping cylinder or gripper circuit on a machining fixture, where the 1/8 in NPT port matches the control valve and the regulator holds a fixed clamp pressure below 0.9 MPa.
Regulating the supply to small air cylinders and air tools at an assembly bench, with the set pressure dialled in once and locked for repeatable part seating.
Providing steady, adjustable air pressure to gauges, sensors or a laboratory test rig, where the -20 to 70 C operating window and fine 0.05-0.9 MPa adjustment suit controlled bench conditions.
Start with the port and flow step: GR200 is the smallest GR size and this unit carries a 1/8 in NPT port, so match it to the line size and air demand of the circuit it feeds - if your consumption sits above what a 1/8 in line comfortably carries, step up to GR300 or larger rather than starving the circuit. Set pressure must fall inside the 0.05-0.9 MPa (7-130 psi) adjustment range; if your process never exceeds 0.4 MPa, the low-pressure L variant of the same series is worth considering. Decide on a gauge: this code (N) ships without one, but gauge-equipped versions are available with square or round dials and MPa, psi or bar scales. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also orderable. Bracket is omitted on this code, though the GR body is panel-mountable either way.
One honest note on sizing: AirTAC publishes GR flow as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the datasheet curve and sizing before you order.
Quick checklist
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes GR-series flow as performance curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your line pressure, set pressure and air demand, and we will confirm the datasheet curve and check the GR200 size with its 1/8 in NPT port is correctly sized for your application before you order.
J means no mounting bracket is supplied (the GR body is still panel-mountable), N means no pressure gauge is fitted, and T means the 1/8 in port is NPT thread. If you need a gauge, a bracket, or a different thread such as PT or G (BSPP), those are available as separate catalogue codes in the same GR200 series.
